EYELETING-MACHIN E.

Specication of Letters Patent.

Patented Aug. 13,1912.

To all 'whom it may concern.'

Be it known that I, JOHN J. DoiDGE, a subject of the King of GreatBritain, reslding at South Framingham, in the county of Middlesex andState of Massachusetts, have invented a new and usefulEyeleting-Machine, of which the following is a specification.

My invention relates to improvements in foot-power machines for settingeyelets and the like, and especially to that type which comprises anormally stationary upper eyelet set, a movable lower eyelet set, saidsets also constituting a punch, and a raceway which is movable into andout of the path of travel of said lower set for delivering eyeletsthereto; and said invention consists generally in improved mechanism foroperating the lower set and the raceway, and in certain other features,all as hereinafter set forth.

One object of my invention is to provide a machine for taking eyeletsfrom a raceway and setting them in stock after punching the holestherefor in said stock, at each cycle of operation of the machine, andin which the eyelet punching and setting and the feeding devices are socombined that a single progressive movement of the operating mechanismtakes an eyelet, punches a hole in the stock and sets such eyelettherein accurately and expeditiously.

Other objects will appear in the course of the following description.

I attain these objects by the mechanism illustrated in the accompanyingdrawings, in which- Figure 1 is a side elevation of a machine whichembodies a practical form of my invention; Fig. 2, a top plan of thestock or work table with its gages, the edge of the table which appearsat the bottom in this view being the front edge thereof, and, Fig. 3, aside elevation in partial section of said machine, showing the operatingmechanism and parts disposed at the opposite extreme to that in whichthey appear in Fig. 1.

Similar figures refer to similar parts throughout the several views.

In Figs. 1 and 3, 1 represents a portion of a table or bench upon whichmy machine is mounted. A frame or support 2, having a base 3 which restsupon and is secured in any suitable manner to the table 1, carries theoperating parts and members of the machine. The front of the support 2is cut away at 4 to accommodate a work table 5, and there is a verticalpassage 6 in said support below such cut-away portion 4; for a plunger7, and a vertical passage 8 through the support above such cut-awayportion for an upper set 9 and an adjustlng screw 10 therefor. The axesof the plunger 7 the set 9 and the screw 10 are in the same verticalline. The upper set and its adjusting screw are in what may be said tobe the head of the frame or support. The back wall of the passage G isslotted at 1l to admit into such passage the front terminal of a lever'12 which is pivoted at 13 to a lug 14 that rises from the base 3 behindsuch slot. An operating lever 15 is pivoted a short distance below itsupper end, at 16, to a lug 17 that rises from the base 3 at the backend. The table 1 and the base 3 are slotted to accommodate the lever 15.The lower portion of the lever 15 is broken olf in Figs. 1 and 3, butsuch lever is of the usual pedal and spring' operated variety. A spring18 ex tends from a suitable lug on said lever to a suitable hookprojecting below the underside of the table 1 and servosto tension thatpart of the lever which is below the pivot 16 forwardly and that part ofthe lever which is above said pivot rearwardly.

Pivotal connection between the upper end of the lever 15 and aprojection 19 rising from the rear terminal of the lever 12 is had bymeans of a bolt 20 extending from said lever 15 into a slot 21 in saidprojection, an anti-friction roller 22 of the usual type being mountedon that part of said bolt that is in said slot. The arrangement of thesemembers is such that, when the upper terminal of the lever 15 is rockedforward and downward, the rear terminal of the lever l2 is carrieddownward, through the medium of the bolt 20 and its roller operating inthe slot 21, and at the same time the front terminal of said lever 12 iscarried upward; and the return stroke of such upper terminal of saidlever 15 restores the lever 12 to its former position. The shape andposition of the slot 2l is in the main responsible for these movementson the part of the lever 12.

A vertical rod 23, which may be adjustable, is set into the base 3 infront of the lever 15, and is designed to afford a stop than thediameter of an eyelet barrel in-V tended to lie and slide between them,and spaced from'the lioor suliiciently to permit the head of the `eyeletto travel between vthe ioor and the adjacent faces of said rails.v Sucha floor is represented at 24, and one of j suchv rails is represented at26. A hopper 27 for eyelets is fastened Von the raceway at the upper,rear end. The floor 24 is suppor-ted by and on a bracket 28, whichbracket is provided with two -horizontal fixed rods 29 and 30 which Vareslidingly mounted in;

lugs `31-31 and 32 on one side of the support 2 there being in this casetwo lugs for the rod 29 and lone for the rod 30. In the lowerportion :ofthe bracket 28 is an irregular-shaped cam-slot 33 in which .operates anl anti-friction roller 34 ,on a stud 35 that prof jects from the rearend of the lever 12. The

aforesaid rear end, including the projection 19, of the lever 12 issituated between the lever 15 and the bracket 28. The construction andarrangements of the part-s just described is such Ythat the downwardmovement of the rear end -of vthe lever 12 causes, through the medium-of the stud 35 and its ro-ller in the cam-slot 33 in the bracket 23,the raceway to movebackward, and the upward movement of said rear zendof said lever 12 causesv said raceway' to move forward, through the samemedium, as will be plainly seen upon referring to Figs. 1 and 3.

Having now outlined my machine in a somewhat general way., I will nextproceed to .take it up more in detail.

The plunger 7 has a bifurcated base 36 to receive the front end or headof the lever 12, and said base is provided with an anti-` frictionroller 37 on `a ,pin or stud 38 above said head, zand with a pin 39below said head,.so that said plunger must follow the head 'in its 'upand .down movement, or in other words, is reciprocated vertically in thepassage 6 by the lever 12.

40 is =a bushing in the upper end of lthe passage 6 for the plunger 7and 41 a setscrew for such bushing. Seated in 4the upper .end .of theplunger 7 .and held against upward .displacement by a set-screw 42 is aset 43 which also constitutes :the male member of a punch. Thevcombination Ipunch and set 43 operates 4in conjunction with the set 9,which latter constitutes the female member Lof the punch, in the usualmanner to punch the hole in the stock, and introduce an eyelet 44 andupset it therein, as represented at 45, in Fig. 3, wherein a piece ofstock is also represented :at 46.

The adjusting screw 10 is Atapped into the passage 8,bears on the `upperyend of the set 9, and affords means for locating said set at a lowerpoint, should occasion require,

, than it is located when its shoulder is against the underside of thehead of the support 2. A set-screw 47, tapped into the front of the headof the support 2 as the set-screw 42 is tapped into the front of theplunger 7, serves to hold the set 9 against downward displacement, andmust be loosened, of course, before attempting to adjust said set.

The set 9 and the screw 10 are .bot-h hollow .so as to allow thematerial punched from `the stock to pass upward and escape through thetop of said screw. 48 is a set-nut for :the screw 10.

Upon loosening the set-screws 42 and 47, the sets 43 and 9 can beremoved andV new ones of t-he saine or a different size substituted,thensaid set-screws are .retightened The machine is able to handle :asmany different sizes of eyelets as there are different sizes of sets,.provided the feed be attended `to in lthe manner hereinafter more fullydef scribed. The sets are changed in the manner just explained. Theshanks of the sets, which fit into the sockets provided to receive them,are always the same regardless of the size of the sets themselves. Thesmall `upper portion of the set 43 isv the part that fits the eyeletAand venters the above-men tioned passage, 49, in Vthe set 9. These setsdo not differ materially in general construction and operation fromother sets in common use for the same purpose.

The table 5 is supportedlfrom the front of the support 2, above =theplunger 7, on two brackets v50 to which said .table is .securelyfastened by screws 51. The base of each bracket 50 isattached to oneside of the support 2 by means of .a pin 52 and a thumb- `screw 53. IInthe center of the table 5 is a hole 54 through which the set 43operates. This table is equipped with two gages for the work, one ofwhich determines the distance in from one edge 4of the stock that 4theeyelets are to be set, and theother of which determines l the distancebetween eyelets. The first of these'gages com-prises a horizontal plateor slide v55 provided at its inner end with a vertical finger 56 whichis directly ybehind the hole 54, and the kother gage comprises ahorizontal strip or slide 57 provided at itsinner .end with a verticallinger 58 at one side of said hole.

The slide 55 rests on the .table 5 :and is adj'ustably held .theretobymeans of a screw 59 anda thumb-screw 60. There is a slot 61 in theslide 55, which extends from a poi-nt near the front edge of said slideback-ward through the rear edge of the same, and the screw 59 passesfrom above through this slot into threaded engagement with the table.The thumb-screw 60 passes from below through a slot G2 in the table intothreaded engagement with the slide 55, such slot (32 being parallel withthe slot (51. Adjustment of the finger 56 is effected by loosening thescrew 59 and the thumb-screw (30, moving the slide 55 backward orforward accordingly as it is desired to set the eyelets farther from ornearer to the edge of the stock, and then retightening said screws.

The slide 57 is held against the underside of the table 5 by means of athui'nb-screw G3 which passes through a longitudinal slot 64 in saidslide into threaded engagement with said table, and the finger 58extends through and operates in a longitudinal slot 65 in the table. Thefinger 58 projects above the top of the table, and its adjustment iseffected by loosening the thumb-screw G3, moving the slide 57 toward oraway from the hole 54 accordingly as it is desired to locate the eyeletscloser together or farther apart in the stock, and retightening saidthumb-screw.

During the operation of the machine, the stock is held with one edgeagainst the inger 56, and moved along in that position after the settingof each eyelet, so that all eyelets set shall be the same distance infrom such edge; and each eyelet as set or immediately after being set isplaced over the finger 58 to determine the position of the next eyelet.

The table 5 is cut away to whatever extent may be necessary toaccommodate the toe of the raceway, and some adjustment for said tableis afforded by slotting each bracket 50 at the base, as shown at 6G, inFig. 1, for the pin 52 and the thumb-screw 53.

The toe of the raceway or that part of the raceway that comes intointimate relation to the set 43 is equipped with adjustable members, oneof which appears at 67, and a spring stop 68 for the lowermost eyelet44. These elements and the manner in which the eyelets are controlledand permitted to be fed by them are fully set forth in United StatesLetters Patent, No. 1,012,999, issued to me December 26, 1911.

The hopper 27, which is a reservoir for the eyelets, has a cover 79 andis provided with the usual internal agitator brush (not shown) which ismounted on a shaft or spindle 81 journaled in the floor 24 and the rearend of the bracket 28. A pinion 82 tight on the lower end of the spindle81, a suitablymounted loose gear 83, an operating plate 85 on the hub ofsaid gear, and a connectingrool 86 having one end pivoted to aprojecting part of said plate and the other end loosely connected with abolt 88 which rises from a lug 89 on the support 2, 1are employed tooperate said spindle. The gear 83 and plate 85 are held on a stud whichprojects below thc floor 24 at one side of the spindle 81., by means ofa washer 99 and a nut 100.

A selector 91 is attached to the hopper 27 over an opening therein toinsure the presentation of the eyelets to the raceway in the properposition, that is, with their heads down on the iloor 24 and theirbarrels projecting at right-angles to said iloor. The base of thisselector is provided with a plurality of notches 92 each of a size andshape to admit of the passage of a single eyelet when resting on itshead, barrel up, on the floor 24. The selector' 91 has two lugs 93 bymeans of which and two screws 94 said selector is fastened against theoutside of the hopper. "lhe above-mentioned eyelet-feeding mechanism andappliance are more fully set forth in the l1ereinbefore-mentionedpatent.

ssuming that the parts are all properly adjusted, the hopper is suppliedwith eyelets and all is in readiness, the operation of the machine isbriefly as follows: lhe stock is placed by the operator on the tableagainst the finger 5G and in the right position relative to the hole 54,and then the operator forces back the long arm of the lever 15 againstthe resiliency of the spring 18 until the short arm of said leverstrikes the stop 23. This action on the part of the operator results inrocking the lever 12 to elevate the plunger 7 and thereby cause the set43 to pick the eyelet immediately above it in the raceway, and `inconjunction with the set 9 punch the hole in the stock, insert theeyelet carried by said set 43 in such hole and upset it therein; and inwithdrawing said raceway from the path of the rising set until theraceway is at the rear end of its travel. Vhile in the act of punchingthe hole in the stock for the eyelet and upsetting the latter the stockis lifted from the table 5, as shown in Fig. 3, but said stock does notriso above the top of the linger 5G. and said hnger may be bent overforward, if desired and as shown, to prevent the edge of the stock whichbears against said linger from passing upward clear of the finger.

The operator next releases the lever 15, and the spriiig 18 then acts toreturn said lever to its former or initial position and so to restorethe rest of the mechanism to the position which it originally occupied,that is to say, the lever 15 elevates the long arm of the lever 12 andso causes the plunger 7 with the set 43 to be depressed, and said leveralso actuates the raceway forward to the position where the lowermosteyelet therein is directly in line with said set and ready to be removedfrom said raceway 'when next the set rises. lVhen the set 43 descendsthrough the hole 54 in the table 5, it leaves the stock or work on saidtable,

and the operator moves it along until the eyelet just set. can beslipped over the finger 5S. The set eyelet is then placed over thefinger 58, and the operator proceeds .to set the next eyelet in the sameway he did the first, the operation or the series of operations eachtime being the same as already fully described.

The operating mechanism for the plunger and the raceway is so timed thatthe latter does not begin to move back until the set 43 has risen intoengagement with the first eyelet; but the backward travel of the racewayis accomplished very quickly when once begun so as to clear the way forthe rising plunger 7 with its set and the eyelet thereon, and theforward movement orp said raceway is also accomplished without loss oftime after starting in order that a new cyelet may be speedily locatedinthe path of the movable set.

Each time the raceway travels forward the brush spindle 8l is caused tomake a partial revolution and consequently to cause the eyelets in thehopper to be agitated and those that are in proper position adjacent tothe selector 91 to be forced out through the latter into said raceway,and it is by this means that the raceway is kept constantly suppliedwith eyelets.

The machine can be operated as fast as the lever l5k can be actuated bythe foot of the operator and the spring 18, the adjustment of the workon the table 5 being practically the only limit to speed.

lt is obvious that numerous departures in the construction andarrangement of some or all of the parts of this machine, such as willreadily occur to one skilled in the art,

Ymay be made without departing from the nature of the invention or goingoutside of the scope of the claims.
